Blue Hour palette
Leafy Crater
A quiet five-stop blue hour arc with a confident middle — #005499 carries the weight and #94c6ff carries the air, with #127cda, #3998f9 and #5da9fc bridging in tetradic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
